Te kimi i te tawhiti mai i tetahi ira ki te rererangi

I roto i tenei whakaputanga, ka whakaarohia he aha te tawhiti mai i te waahi ki te rererangi, me te aha te tauira ka tatauhia. Ka wetewetehia e matou tetahi tauira o te whakaoti rapanga mo tenei kaupapa.

Tātai Tawhiti Ira-ki-Mahere

Ki te kimi i te tawhiti mai i te waahi karekau mo tetahi rererangi, me whakaheke te poutokoto mai i tera ki tenei rererangi.

Roa Tiaki (d) ko te tawhiti e hiahiatia ana.

Tātai mō te tātai

Te tawhiti i te waahi XNUMXD mai i tetahi waahi O me nga kotahitanga (O_x, KOU_y, KOU_z) ki te raina tika i homai e te whārite Ax + By + Cz + D = 0, ka whakaarohia e whai ake nei:

He tauira o te raruraru

Me kii he waka rererangi to tatou 3x – 4y + 2z – 5 = 0. Kimihia te tawhiti mai i tera ki te waahi O (2, 0, -6).

Te whakatau:

Ko te whakakapi i te tauira i runga ake i nga uara e mohiotia ana ka whiwhi tatou:
